For good reason, the slave is already fixed ready when his mistress Miss Yara presents her plans. She wants to use her new toy. A spiked ring that she had specially adapted so that it can be attached like a penis cage. The spikes thus become indomitable. The skin can no longer slip a bit. The discomfort becomes hellish. Even as she puts the ring on, Cosmo's protest begins. His feelings are so strong that he seriously tries to fight back. Of course, the restraints are unyielding and Miss Yara calmly and coordinatedly indulges in her sadistic game. She will take her time tormenting her victim. Over and over again she will bring the slave close to climax so that the feeling is at its worst. He tries not to get hard to relieve the feelings. He is losing. As always. Despite loud protests, Yara finally brings the desperate slave to climax in a rush of feelings and pleasure. With this Cosmo experiences the strongest feelings he has ever had to endure.
